To all whom it may concern.

Be it known that I, GEORGE B. WARNER, a citizen of the United States, residing at Fitchburg, in the countyof Worcester and State of Massachusetts, have in-vented an Improvement in Paper-Tube Machines, of ,which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The invention to be hereinafter `described relates to machines for making paper tubes and more particularly to such machines that form the. tubes by winding layers of paper upon each other, and generally known as paper .winding machines.

The aims and purposes of the present invention are to provide a machine of the general character stated that will be more efficient in operation, simple in construction, and wherein the product can be secured more expeditiously and economically; all as will hereinafter appear from the following description in connection with the accompany ing drawings of one form of means for carrying the invention into practical effect, it being understood that the invention in its true scope is definitely set forth by the claims.

ln the drawings: Figure 1 is a front elevation of a machine embodying the features of the present invention, parts being broken away; Fig. 2 is a side elevation of the machine shown by Fig. l, looking from the Vright hand side thereof; Fig. 3 is a view sim- :ilar to Fig. 2, looking from the opposite side of the machine; Fig. 4 is a detached detail showing features of the stopping mechanism; Fig. 5 is an enlarged sectional View on the line 5 5, Fig. 1; Fig. 6 is a section on the line 6-6, Fig. 5; Fig. 7 is an enlarged detached sectional detail of the paper roll carrying device; Fig. 8 is a sectional view thereof on the line 8-8, Fig. 7; and Fig. 9 is a detail of the adhesive applying roller.

The main frame of the machine may be of suitable character to support the operating parts, and, as shown, it comprises thev end uprights 1 and 2 and the intermediate upright or frame 3 which may be properly braced and connected together in a longitudinal direction by means of the tie beams or braces 4, Fig. 1. The frame thus formed constitutes the sustaining element for a paper roll from which the paper is drawn and wound upon a suitable mandrel likewise surface of the paper with the adhesive at such times as desired To produce a desired tension .on the paper sheet as it is being wound upon the mandrel, a friction device Acooperates with the paper roll, and when the desired number of windings have been made on the mandrel, a stopping device automatically stopsthe machine and applies a brake to prevent over-running, all of which parts and others thus sustained in operative rela` tion on the main frame will now be more fully described as to details and operative functions.

Mounted in suitable bearings 5, 5 on the machine frame is the main driving shaft, 6 carrying the loose pulley 7 which may be driven from any suitable source of power by driving connection, such as a belt, not shown.

r1"he invention contemplates imparting rotatlve movement to the paper winding man drel through the driving shaft when the latter is operatively engaged with the driving pulley, but when the driving pulley is disengaged from driving connection with the driving shaft, the invention contemplates quick arrest of the mandrel to the end that over-running shall be prevented and theI mandrel be promptly brought to rest when the tube or barrel is completed. As one means to these ends, there is secured to the driving shaft 6V adjacent the loose pulley 7, a collar 8 having a liange 9 surrounding a portion of the hub 10 of the driving pulley, said collar alsohaving pivoted thereon at 11, Fig. 1, an arm 12 for acting upon a friction band 13 to clamp the collar 8 and pcrforce the shaft I6 to the hub of the driving pulley 7. Similarly, there is secured to the shaft 6 a collar 11 having a flange to which is pivoted the arm 15, the end 16 of which is adapted .to operate a friction band 17 to clamp the In order to operate the above described device to clamp the shaft 6 to the driving pulley and release it from the braking power of the band 17, and conversely to release it from the driving pulley and apply the braking power of the band 17, there is splined to the shaft 6 a double cone 18 having a groove 19 which is engaged by an arm 20 of a stopping and starting device to be hereinafter described. Secured to the driving-shaft 6 is a pinion or gear 21 which is operatively engaged with a larger gear 22 secured upon the mandrel driving shaft 23, said shaft being suitablygsastained in bearings 24 and 25 27, by means of suitable pintles or hinge pins 28, 28, the construction being such that the mandrel carrier or yoke 26 may be swung horizontally on the said pins, as will more fully appear.

The mandrel carrier or yoke 26 has a central head portion 29,7Figs. 1 and 5, which serves to support the mandrel spindle 30 and permit the same to be rotated through connections with the mandrel driving shaft 23.

In the present form of the invention the head 29 is centrally bored to provide a bearing for a rotatable sleeve 31 having a flange 32 and an anti-friction device 33 interposed .between said flange and the end of the head 29, see Fig. 5'. At its opposite end the sleeve 31 is provided with a screw thread connec- Ytion 34 with a yoke 35 forming, with a similar yoke 36 secured to the end of the mandrel driving shaft 23, a universal joint connection between the mandrel driving shaft and the mandrel spindle, the turning point of said universal joint beingv in the vertical line of the hinge support of the mandrelv carrler or yoke. From this construction it will be seen that while the mandrel carrier or yoke may be swung horizontally for purposes of removing the windingson the mandrel, the driving connection between the mandrel spindle and mandrel driving shaft remains undisturbed. In order to limit the swinging movement of the mandrel carrier or yoke, a stop 37, Fig. 5', may be employed, said stop being formed as an adjustable screw mounted in the arm 38 projecting from the main frame.

Y Mounted on the mandrel spindle 30 is the mandrel which may be of desired construction, and is herein shown as formed of two parts 39 and 40 relatively movable horizontally in an inclined direction for the purposes of collapsing and expanding the mandrel. One of these parts, such as 39, is supported on the twol heads 41 which are secured by suitable means, such as the screws 42, to the mandrel spindle 30. The head portions 41 of the member 39 are provided with inclined ways 43, Fig. 5, which are preferably dovetailed, as indicated in Fig. 6, and in which slide the supporting portions 44 of the other member 40 of the mandrel. To effect this sliding motion of the member 40 with respect to the member 39, the portions 44 of the member 40 are connected byivSO a bar or rod 45, to which is pivoted a linkg 46 jointed at 47 to a hand lever 48, Fig. 5,- pivoted at 49' to a yoke 50 secured to the. other member 39 of the mandrel, the construction being such that upon manipula tion of the handle 48, the member 40 of the mandrel may be moved to collapse or expand the mandrel as will be cleaily evident from Fig. 5 and to those skilled in the art.

The mandrel in the present machine is shown of large size, more particularly adapted for the winding of paper in the formation of paper barrels and the like, but it is to be understood that the mandrel may be appropriately formed and of a size to suit the conditions of use or the product to be formed. In any event, however, the free end of the mandrel spindle 30 should be supported in order to relieve the strain at the other end of the spindle, and to this end the present invention contemplates a slide 51, Fig. 5, having a socket 52 in its end for the reception of the end of the mandrel 30, said slide 51 being supported and movable longitudinally in a bracket 53 with which it may have a splined connection, as indicated in Fig. 5. For operating the slide 51 to engage and disengage the end of the mandrel 30, a hand lever 54 is preferably pivoted at 55 to a suitable bracket and has a pin and slot connection 56 with said slide 51, and in order tb hold the slide 51 in its engaged position with the end of the mandrel spindle 30, a spring 57, Fig. 5, is secured to the handle 54 and has a shouldered end portion to engage a suitable socket in the bracket 53, as will be clear from Fig. 5, the construction being such that upon force being applied to the handle 54 the spring may be engaged with or disengaged from its holding socket in the bracket, but will under ordinary conditions of use hold the parts in operative relation, as indicated by Fig. 5. With a machine of this general character, wherein the paper is wound upon a mandrel in successive convolutions to forml the desired product, whether it be a barrel of large or a tube of smaller diameter, it is desirable that the paper be continuously drawn from a source of supply and be held under tension, and that suitable means be employed for regulating the tension and taking up any slack in the paper web. To this end, the present invention con templates supporting in the machine a roll of paper and drawing from such roll under suitable tension the convolutions of paper that are wound upon the mandrel.

Mounted in suitable bearings 58 of the machine frame is a paper roll shaft 59 having a sprocket wheel l60 secured thereto, said sprocket wheel being appropriately driven by a sprocket cha-in 61, Figs. 1 and 2, from a hand shaft 62 supported in suitable bearings 63 of the machine frame and having a sprocket wheel 64 engaging the said sprocket chain. Secured to the hand shaft 62 is a hand wheel 65, Figs. 1 and 2, whereby the hand shaft 62 and, perforce, the paper oll shaft 59 may be appropriately turned upon manipulation of the hand wheel 65. Mounted on the paper roll shaft 59 is a friction disk 66, Figs. 1 and 2, about which passes a friction band 67, one end 68 of which is secured to the machine frame and the other end 69 of which is secured to a shoe 70 having a screw thread connection witha shaft 71, Fig. 2, provided with a hand wheel 73 by which it may be turned, the construction being such that upon manipulation of the hand wheel 73 the shaft 71 and, perforce, the shoe 70 may be adjusted to tighten or loosen the friction band 67 upon its friction disk 66 and thereby adjust the tension of said band, as will be evidentA to one skilled in the art.

The paper roll from which the paper is drawn is represented at 74 in Figs. 1, 2 and 7, said roll being preferably o a size to provide a long sheet of paper material and having passed through the center thereof for its support a shaft 75. In order that the paper roll may be mounted to rotate with and not independently of the shaft 75, the latter is preferablylprovided with a sleeve 76, one at each end of the paper roll 74, as 'ndicated in Fig. 1, and one of which is inflicated in detail in Fig. 7. The sleeves 76 are preferably7 of conical form, as indicated, and when forced inward or toward each other are adapted to engage the interior of the paper roll as indicated in Fig. 7 and form a driving connection between said paper roll and said sleeves. The sleeves 76 are preferably loosely mounted on the shaft 75 in order that they may be adapted to rolls of different widths and in order to readily permit them to be removed from the shaft 75 and then, when adjusted into engaging position with the paper roll, to be clamped in place. To these ends, the sleeves 76 have a bifurcated portion as indicated at 77, Fig. 7, said. bifurcated portions being connected by a setscrew 78, they construction being such that when the set screw 78 is released, the sleeve 76 to which it is connected may be slid longitudinally of the shaft 75 and when the set screw 78 is tightened the part 77 of the sleeve may be clamped IiXedly to the shaft 75 to cause said shaft and the roll 74 mounted thereon to turn together.

In order to provide a detachable driving connection between the paper roll shaft 59 and the shaft 75 on which the paper roll is mounted, these two parts are provided with interengaging portions, one form of the invention in these respects being indicated in Figs. 7 and 8.

In the form of the invention Shown, the paper roil shaft 59, on its end adjacent the paper roll, is provided with a shoe or socket piece 79 which is rigidly secured to said paper roll shaft. This shoe or socket piece extends beyond the end of the shaft, see Fig. 7, and said extended portion is provided with a socket or opening 80 leading to its central portion, as indicated in Fig. 8. The end of the shaft 75 carrying the paper roll is adap-ted to enter the socket or opening S0 and seat itself in the shoe or socket piece 79, substantially as indicated in Figs. 7 and 8; and the end of said shaft 75 has a key or projecting piece 81 secured thereto by fsuitable screw connections 82, Figs. 7 and 8, said key being of a dimension to properly fit the .opening or socket 80 in the shoe 7 9. When the end ofthe shaft 75 and its key 81 are seated in the shoe 7 9, a collar 83 which is adapted to move longitudinally of the shoe 79 and which embraces said shoe as in dicated lin Figs. 7 and 8, is slid along the shoe to overlap the end of the shaft 75 and its key 81, and is then secured in place by a set screw 84, Fig. 7. From the construction described, it will be apparent that rotative movement imparted to either the shaft 59 or the shaft 75 will impart to the other ro tative movement corresponding thereto, and that when it is desired to remove the paper roll 74, or its shaft 75, and to place a new supply of paper in the machine, it is only necessary to loosen the screw 84, slide the sleeve 83 to the right, Fig. 7, and lift the end of the shaft 75 from the shoe 79, whereupon the shaft 75 may bemoved longitudinally to the right, Figs. 1 and 7, to disengage said shaft from its machine frame sup ports; or if such removal be not desired, the

end of the shaft 75 may be raised and after removing-the conical sleeve 76 in the manner already described, a new roll of paper may be placed upon the shaft 75 and the parts again adjusted for coperation in the manner hereinbefore explained.

When the paper is being wound upon the mandrel, it is desirable that the first layer of paper be not gummed or supplied with an adhesive, but that each succeeding layer be .gunimed or supplied with an adhesive on that side nearest to the preceding layer or nearest the mandrel. In the present form will be obvious to those skilled in the art.

Inasmuch as the first layer of paper wound i upon the mandrel is not to be supplied with an adhesive, the roll 88 is mounted so that it may be lifted from its cooperating roll 89 in the adhesive receptacle 90. As one form of means to this end, the roll 88 is mounted in the arms 91 pivoted at 92 to the machine frame and having downwardly converging cam portions l93 and 94, the former of which acts as a carnqto cooperate with a projection or cam piece 95 securedv to a shaft 96 carrying the hand wheel 97, the construction being such that upon turning the hand wheel 97 clockwise, the roll 88 may be. lifted from the roll 89 and the paper 85 traveling from l the'hand wheel 97 is rotated in the same or kto the paper roll 74 to the mandrel may proceed to the latter without having its surface supplied with an adhesive. After one or, if desired, more layers of the paper has been thus wound upon the mandrel without adhesive supplied to its surface, the-hand wheel 97 may be turned contra clockwise to permit the rolls 88 and 89 to approach and cause the surface of the paper 85 to contact with the roll 89 and be by it supplied with an adhesive in the further operation of the machine.

- The co-acting cam portion 93 and 95 hereinbefore described are so related that when the hand wheel 97 has been turned to lift theV roll 88 and the paper 85 from the roll 89, said cam portions will maintainythe parts in elevated position and out of contact until opposite direction, as will be readily understood. v

Since the adhesive material is in liquid form, and is lifted by the roll 89 to supply the surface of the paper 85 with the adhesive.V it is desirable. in some instances at least, that the roll 89 have its surface somewhat roughened, so that a proper supply of .an adhesive may be appliedf to the surface of the paper. As one form of means to this end, the paper roll 89 which extends into the liquid adhesive in the chamber ,90 is preferably provided with corrugations or other like small indentations 98 which may conveniently extend circumferentially about the roll as indicated in Fig. 9; their direction, however, with respect to the circumference of the roll may be changed when circumstances seem to dictate.

action' shall be effected without over-run- 70 ning or drawing more paper from the roll than is necessary to complete the number of layers desired in the finished product. Inasmuch also as different sized mandrels may be used in the same machine, and different sized barrels, tubes or the like may be produced, it is desirable that the single machine shall in its stopping mechanism provide means to effect the intended purpose throughout they various range of adaptation as to size of;

mandrels. This characteristic of the invention will now be described.

Mounted in suitable bearings 99 secured' to the top tie beam 4 of the machine frame is a stop rod 100 carrying the arm 20, Fig. 1, for operating the double cone 18 hereinbefore described. Mounted upon the stop rod 100 is a spring 101 interposed between one of the brackets 99 and a collar 102 secured to the stop rod, said spring acting normally to move the stop rod 100 to the left, Fig. 1, and cause the cone 18 to disengage the driving pulley 7 from the driving shaft and to apply the brake to the driving shaft as hereinbefore noted. The stop rod 100 has a collar 103 secured thereto and connected by a link 104, Fig. 1, to a handle 105 pivoted at 106 to the bracket 99 at the left, Fig. 1, whereby upon movement of the handle the stop rod 100 may be moved longitudinally for the purposes of operating the clutch members as above pointed out. Secured to the stop rod 100 by the set screw 107 is a stop sleeve or collar 108 having a notch or shoulder 109 which is adapted to engage to the right of a stop finger 110, Figs. 1 and 4, said stop finger 110 being pivotally 1nount'- ed at 111 upon an arm 112 extending from a head 113 mounted on a rod 114 disposed parallel to the stop rod 100. Between the stop finger 110 and the arm 112 is a spring 115 and its limiting pin 116, said saring normally tending to turn the stop nger contra-clockwise, Fig. 4, to cause its upper rounded end portion 117 to engage the shoulder 109 of the collar 108. Pivotally mounted at 118 on the lower end of the stop finger 110 is a shoe 119, the end of which is adapted to bear upon the convolutions of the paper windings 120 on the surface of the mandrel 39, the construction being such that when the number of windings on the mandrel have reached the desired point, the stop finger 110 will have been turned about its pivot 111 to an extent sufficient to withdraw its upper end 117 from in front of the shoulder 109 of the collar 108, thereby freeing the stop rod 100 to the action of its spring 101, with the result that the double cone 18 will disconnect the pulley 7 from Yao driving relationl with the shaft 6 and simultaneously therewith will apply the brake to the driving shaft to bring the mandrel promptly to rest.

Inasmuch as mandrels'of different sizes are to be employed in the-same machine, the shoe 119 is pivotally mounted to the stop linger 110 at 118 and is held in adjusted position by a pin and slot connection 121 with said stop finger, the purpose of such adjustable swinging connection being to permit the surface of the shoe 119 to always bear radially against the surface of the ,paper windings, regardless of the sizeof wumandrel employed. The head 113 carrying the arm 112 is likewise rotatably adjustable on its supporting shaftI 114 to accommodate "the stopping device to mandrels of different sizes; and as one means of adjusting and securing the head 113 in desired position, it is connected by a bolt and slot connection 122, F ig. 4, to a depending arm 123 of a sleeve 124 carried by the sleeve 108, Figs. 1 and 4, said sleeve 124 having a part 125 engaging the stop rod 100 to maintain it or rod 114. V

From the construction described as one embodiment of the present invention, it will be noted that regardless of the size of mandrel employed and the diameter of the barrel or other paper cylinder produced, the stopping device may be adjusted to cause the shoe 119 to bear directly upon the surface of the paper being wound, and the head 113 carrying the arm 112 may be likewise properly adjusted with relation to the size or diameter of the cylindrical barrel or tube to be produced.
